Specification of Letters Patent.

Patented Aue'. 7, 1917.

` Application filed December 30, 1915. Serial No. 6f),327.

To all whom t may concern.'

Be it known that I, MAURICE LACHMAN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Felices, of which the following is a specilication.

My present invention relates to the construction or adaptation of metallic fencing whereby it can be shipped knock-down and readily assembled at the place of installation.

rThe object of the invention is to provide a fence structure which can be shipped in disassembled rcondition and `thereby save freight and handling charges and at the same time attain a structure which when assembled will be as strong and rigid as though built complete at the factory. The object is also to attain such a structure by using as few parts as possible.

To these ends the invention'consists in the improved fence structure hereinafter more particularly described and then specified in the claims.

In the accompanying drawings, Figure l is a front elevation of a fence structure constructed in accordance with this invention.

Fig. 2 is a vertical transverse section taken on the line 2-2 Fig. l, the picket being shown in elevation.

Fig. 3 is a transverse section through one of the rail members taken on the line 3 3 Fig. l.

Fig. 4L is a transverse section through the rail members before assembling.

Fig. .5 is a side elevation of the spacing member for the rails which is also the fas tening device for securing them together.

Fig. 6 is a partial section and elevation of a part of a modified construction in accordance wit-h this invention.

Fig. 7 is a section taken through one of the pickets of the form shown in Fig. 6.

The fence structure herein shown and described becomes, when'assembled, a gradable fence; that is, one in which the fence after completion will conform to any grade of the ground upon which it is to be erected but it will be understood that the invention is equally applicable to structures in which the rails and pickets are rigidly and immovably secured to each other after assembling the members.

In the drawings the metal fence pickets are indicated at l, while 2 and 2 indicate channel-shaped bars arranged in pairs back to back in the completed fence and each pair forming one of the rails of the fence. Between the bars of a pair the pickets l are disposed.

In the construction shown in Fig. l each picket is provided with an enlargement or ball-shaped part 8 at the desired points of intersection with the rail members. The enlargement seats in suitably formed cavities or recesses as shown in Fig. 2 formed in the opposed bases of the rails 2, 2', the enlargement being preferably frec to swivel in the cavities.

5 indicates a fastening member to secure the rail bars 2, 2 to each other and also forms a spacing' member determining the distance between the rails 2 and 2 so that the rails will not bind on the pickets when it is desired to have the pickets free to swivel. In the form illustrated in Fig. l,

i the fastening' members 5 are disposed in the spaces between the pickets.

rlhe members have an enlarged body part, one end of which is provided with a teat or projection 6 surrounded by an annular groove 7. The member 5 is secured to the rail member 2 by means of the projection 6 preferably by electrically welding it to the rail in a well known manner, the attendant bur occasioned by upsetting the metal in the welding operation being taken in the groove 7 whereby the edge of the body of the member 5 bears against the surface of the member 2. The opposite end of the member 5 is provided with a projecting nib or shank 8. This nib or shank is adapted to fit into a hole or perforation 9 in the rail bar 2 and when assembled the end of the nib is headed to clench and secure the rails 2 and 2 to each other, the rail being effectively held between the headed end of the nib and the end of the body portion of the member.

W'hen shipped, the parts are in knockdown or dis-assembled condition, the rails 2 being provided with any desired number of fasteners 5 welded thereto. The rails 2 are provided with the same number of perforations 9 to receive the fastening nibs 8. When desired to assemble, it is merely necessary to place the pickets in proper position and position therails 2 with the fastening nibs 8 in the perforations 9 in the rails 2 and then hammer down the ends of the nibs as illustrated in Fig. 3.

Iith reference to Figs. 6 and 7 the spacing and fastening member 5 also performs the function of being the pivot or support for the pickets. In this case the body of the member 5 is circular and the pickets are provided with a hole through which the member 5 passes. The member 5 is secured to the rails 2 and 2 as in the previous form described.

It will be understood that the invention is not limited to the constructions shown and described which are for the purpose of illustration only.

What I claim as my invention is l. In a knockdown fence, the combination l with a pair of coperating rails between which the picket is held, a spacing member projecting from the inside of one of said rails and forming at its free end a bearing for thek opposite rail, said spacing member being provided with a fastening nib on its end passing directly through said opposite rail for securing the same against the end of said spacing member.

2. A knockdown fence comprising a pair of rails between which the picket is held, a

spacing member permanently secured to the inside of one of them and projecting therefrom to form at its end a bearing against which the inside of the opposite rail may be fastened and a fastening nib projecting from said spacing member through a hole in said opposite rail to secure the same against the end of the spacing member with the picket included between said rails.

3. A knock--down fence comprising a pair of rails between which the pickets are held and a fastening device for securing said rails together, said fastening device being permanentlyT secured to and projecting from the inside of one of the rails and having a projecting nib adapted to pass through a perforation in the other rail and fasten the rails together.

4. A knock-down fence comprising a pair of rails between which the pickets are held and a fastening device for securing said rails together, said fastening device being welded to one of said rails and provided with a fastening nib for securing the other rail.

5. A rail for fences having a metallic block permanently secured thereto and a projecting nib projecting from said .block for engaging and securing a cooperating rail to form a double rail fence having the picket members secured between said rails.

Signed at New York, in the county of New York and State of New York, this 28th day of December, A. D. 1915.
